HOG-FEEDING TROUGH.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed April 9, 1914. Serial No. 830,631.

To all whom it may concern:

Be it known that I, EDWARD CARLSON, a citizen of the United States,residing at Parkers Prairie, in the county of Otter-tail and State ofMinnesota, have invented certain new and useful Improvements in Hog-Feeding Troughs; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to provide an improved feed troughespecially adapted for use in feeding hogs, and to such ends, generallystated, the invention consists of the novel devices and combinations ofdevices hereinafter described and defined in the claim.

The invention is illustrated in the accompanying drawings wherein likecharacters indicate like parts throughout the several views.

Referring to the drawings; Figure 1 is a perspective view with partsbroken away, showing the improved feed trough; and Fig. 2 is atransverse vertical section taken on the line at {v of Fig. 1.

The trough is made up of an inverted V- shaped bottom plate 1, endplates 2, .side plates 3 and cover plates 4. The V-shaped bottom plate 1is extended at both lower edges to form feed troughs 5, outward of thelower edges of the side plates 3. The side plates 3, as entireties, arevertically adjustable, so as to vary the rate of feed from the hopper orbody of the feed trough, into the troughs 5. plate 1 are riveted orbolted to flanges of angle iron, corner strips 6, and the verticallyadjustable side plates 3 are adjustably secured to the inturned flangesof said corner angles, by slot and bolt connections 7. The downwardlyflaring corner angles 6 are shown as extended at their lower ends toafford supporting legs 6 that may either rest directly upon the ground,or may be secured to wooden supporting beams 8, which beams may beextended either transversely, or 1ongitudinally of the trough. The sideedges of thecover 4 are extended downward at 4 far enough, so that theywill overlap the upper edges of the adjustable side plates 3, even whenthe latter are moved downward The end plates 2 and bottom against thebottom plate 1. Preferably, the cover 4 is made in two parts orsections, two sections at their abutting edges being hinged together andto the top of the hopper, by a hinge rod 9. Preferably, angle strips 10are secured to the upper edges of the end plates 2, and the hingedtopplates 4.- are provided with depending end flanges 4 that overlap thesame. Also, the hopper ispreferably divided into two compartments, by acentrally located partition 11 rising from the ridge of the bottom plate1 and secured at its ends to the end plates 2.

Hitherto, in feed troughs of the hopper type, it has been customary toprovide the side plates that overlie the feed troughs proper withsupplemental vertically adjusted sections for regulating the feed fromthe hopper into the feed troughs.

One of the chief features of this invention consists in making theseside plates complete and adjustable, as entireties, to regulate the feedfrom the hopper into the feed troughs; and another feature consists inproviding the cover with flanges that overlap the upper edges of theside plates in all adjustments of the said side plates, so as to preventopening of the hopper when the side plates are lowered, so as to cut offthe supply of feed from the hopper into the feed trough.

The sections of the hinged cover 4 may, as is evident, be independentlyraised, so as to afford independent access to the compartments of thehopper. The feed trough described, may, of course, be made in all sizeseither as to length or other proportion. All of the plates thereof, arepreferably made from galvanized commercial rolled metal sheets. Inactual practice, the device has been found highly eflicient for thepurposes had in view.

What I claim is:

A hopper having a pair of inverted, laterally-spaced angle strips,having at their ends floor-engaging feet, an inverted V- shaped bottomplate secured to the horizontal flanges of said angle strips, end platessecured at their lower edges to the vertical flanges of said anglestrips and having flanges at their vertical edges, a hinge rodconnecting said end plates, side plates slidably mounted as entiretieson the vertical.

flanges of said end plates, a partition seofitheside plates; being bentupward to afcured to said end plates and extending upi foi'd 't ofighs.
